Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed November 13, 1919. Serial No. 337,765.

To all whom it may concern:

Be it known that we. CHAnLns Sorrows and LOUIS H. Knroknn, citizens ofthe United States, residing at Monroe, in the parish of Ouachita andState of Louisiana, have invented a new and useful Hairpin, of which thefollowing is a specification.

This invention relates to improvements in hair pins.

An object of the invention is to provide a hair pin which cannot workloose in and will not tear the hair.

Another object is to provide a hair pin which will grip the hair firmlyby any one of three separate locking means.

A further object is to provide a hair pin made from a single piece ofwire, which is simple, strong, durable and may be economicallymanufactured.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawing forming part of this specification, with the understanding,however, that the invention is not confined to any strict conformitywith the showing of the drawing, but may be changed and modified, solhng as such changes and modifications mark no material departure fromthe salient features of the invention as expressed in the appendedclaims.

In the drawing Figure 1 is a plan view of the wire as it appears afterthe first step in the manufacture of the hair pin.

Fig. 2 is a similar view of the same as it appears after the secondstep.

F 3 is a similar view showing the third step, with the twist formedintermediate of the ends.

Fig. 4 is a side view showing the completed hair pin.

Fig. 5 is an edge view looking fromthe right side of Fig. 4.

Fig. 6 is an edge view looking from the left side of Fig. 4.

Fig. 7 illustrates a slight modification of the invention.

A single piece of wire 10 is used to form the hair pin constituting thepresent invention. This wire 10 is first looped intermediate its ends asindicated by 11, the loop 11 being elongated, and having a length whenformed substantially equal to one-half of the length of the looped wirewhose free ends extend beyond the ends of the loop and form the legs orshanks of the pin. This loop 11 is then bent inwardly intermediate itsends to form the two symmetrical loops 11 and 11 as shown in Fig. 2. Astralght section 12 then divides the two loops from each other. Then thetwo loops and the wire as a whole are given a plurality of twists 13,where the straight sectlon 12 formerly was. These twists preventdisplacement of the loops with respect to the wire. The final step inmaking the hair pin is to take the free ends of the wire and the loopsand bend the same toward each other until the free ends lie nearlyparallel and one of the loops. as 11", overrides the other 11*.

The completed hair pin. as seen in Fig. 4, has the shanks or legs of thepin of a length substantially twice that of the length of the loops. Thetwo loops are the same length and are held by the resiliency of the wirein juxtaposition, inclosed by the free ends. The twists 13 lock theloops in place in such a secure fashion that no solder is necessary.However, we desire to use solder in addition to the twists, or even inplace of the twists, if that seems desirable. The loops are symmetricalwith respect to each other. and each lies inclosed between the two legsor shanks, with one side of the loop in contact with the correspondingfree end of the wire, and the other side of the loop crossing oroverlapping the corresponding side of the second loop, as indicated at15. In other words, each loop is made up of a straight side which issubstantially parallel with the shank and an inclined side which crossesthe inclined side of the other loop, as shown clearly in Fig. 4. Thefree ends of the loop are each flared or bent outwardly as at 14, so asto lie out of the plane of the wire shanks.

In the modification shown in Fig. 7, the same construction is employed,except that instead of using straight wire throughout as the previousfigures disclosed, corrugated wire is used, with the result that each ofthe loops has a corrugated section 17 and ea ch of the shanks has acorrugated section 16. The corrugations may be otherwise dis posed. Wedesire to employ corrugations or not as we see fit, and do not wish tobe limited to a construction employing either merely straight or merelycorrugated wire.

The special feature of this invention which is believed to distinguishit from all other devices of its kind is the provision of three separatelocks or locking points by which it is held securely in the hair. ()nelock is that provided between the two juxtaposed loops, the other twoare provided between the sides of either loop and the adjacent leg orshank. By the present construction the user of one of these hair pinshas at her disposal for use any one of these locks, or look ing means,that may be desired. The hair pin is held firmly in the hair under allconditions of service and can only be released by separating the loopsfrom each other or from a shank. The out-turned ends of the loop make iteasy to insert the hair between the juxtaposed loops. The device beingformed of a single piece of wire is adapted for quantity production byautomatic ma chinery, and is strong and durable.

hat is claimed is 1. A hairpin made of a single piece of flexible wirebent into an elongated longitudinally extending loop intermediate itsends, said loop in turn having a bend inwardly toward the wire and beingsecured to the wire intermediate its ends to form two smaller loops, thetwo loops being in overridin relation.

2. A hair pin consisting'ot' a single piece of flexible wire, said wirebeing bent intermediate its ends and having a pair of juxtaposedoverlapping loops, and shanks or legs inclosing said loops, said hairpin thereby providing three locking means by which it may be held in thehair, one of said locks being formed between said loops, the other locksbeing formed between each loop and the adjacent shank or leg.

3. A hair pin formed from a single piece of flexible wire, said wirehaving a pair of symmetrical overlapped loops, and apair of shanks orlegs inclosing said loops with the ends of said shanks or legs lyingbeyond the ends of said loops, said hair pin having three locking meansto hold it in the hair, two of said locks being formed by the sides ofthe loops cooperating with the shanks or legs, the third lock beingprovided by the two loops.

4. A hair pin, formed from a single piece of flexible wire, said wirehaving a pair of symmetrical overlapped loops, and a pair of shanks orlegs inclosing said loops, said shanks and loops being united by aplurality of twists, with the ends or said shanks lying beyond the endsof said loops.

5. A hair pin formed of a single piece 01 flexible wire, a pair ofsymmetrical loops formed intermediate the ends of the wire, and meansprovided at the meeting point of the loops to hold them in fixedrelation with the wire, the remaining portion of the wire beyond theloops constituting the legs or shanks of the pin, each of said loopshaving a straight side in uxtaposition to the shank, and an inclinedside, the inclined sides crossing each other between the free ends ofthe wire, the loops being held in overlapping relation by the resiliencyof the wire.

In testimony that we claim the foregoing as our own, we have heretoafiixed our signatures in the presence of two witnesses.
